Definitions

  • the present invention relates to an automatic air coupling for a rail vehicle, the rail vehicle being designed in particular in the form of a freight car, in detail according to the preamble of claim 1.
  • Automatic air couplings are conventionally used in rail vehicles intended for passenger traffic and are part of the automatic train coupling there.
  • the automatic air coupling is used to couple the main air line between the individual rail vehicles of a train, that is, between the individual wagons, whereby wagons are both railcars and pulled / pushed wagons.
  • the necessary air pressure must be built up in the main air line of the train in order to release the brakes of all coupled rail vehicles. Conversely, if the air pressure in the main air line falls, the respective rail vehicle is braked.
  • the air coupling is automatically activated when two automatic train couplings are driven against each other and a secure mechanical connection is established between the train couplings.
  • the mouthpiece of the respective air coupling is positioned centrally on the upper edge of the face plate and a flow channel for the compressed air, in which a valve is arranged, connects to the mouthpiece.
  • the flow channel opens beyond the valve, as seen from the mouthpiece, in a compressed air nozzle to which a compressed air hose or a compressed air pipe of the corresponding rail vehicle can be connected in order to establish the connection to the brakes or to the other end of the rail vehicle and the air coupling provided there.
  • the valve in the flow channel is actuated mechanically by the so-called coupling lock, more precisely by its main bolt, which is rotated by a so-called frog connected to it when the pulling couplings are moved against each other.
  • the coupling lock more precisely by its main bolt, which is rotated by a so-called frog connected to it when the pulling couplings are moved against each other.
  • Generic automatic air couplings have an extension of the coupling lock or the main pin, the extension in the form of a shaft can be connected to the coupling lock or the main pin in a rotationally fixed manner and is provided with a cam which, when the shaft is rotated, the valve in the sense of opening the flow channel operated during the coupling process. During the uncoupling process, the cam is rotated back with the shaft and releases the valve, which is then closed by the force of a spring accumulator and blocks the flow channel.
  • valve The position of the valve or of a valve body of the valve which works together with a valve seat is thus dependent on the position of the coupling lock.
  • the valve In the ready-to-couple position, the valve keeps the flow channel and thus the main air line closed. In the coupled position, the valve keeps the flow channel and thus the main air line open.
  • Such automatic air couplings are not conventionally used in freight wagons. Rather, simple pipe sections are coupled here via seals on the face in order to connect the main air line of two rail vehicles to one another. This makes it possible to design such couplings and all of the main air lines with a particularly large flow cross section. The great length of trains with freight wagons is remarkable. If the clutch breaks, the pressure drop in the main air line must spread from vehicle to vehicle starting from the break point in order to brake all vehicles together. High demands are therefore placed on the speed of propagation, also known as the speed of penetration. In particular, according to railway standards, a minimum breakthrough speed of 250 meters per second is specified.

  • DE 102016 104 188 A1 discloses a device for activating at least one functional component of an automatic central buffer coupling, a shaft that can be rotated about an axis of rotation is provided with three cams, the first and second cams actuating valve assemblies and the third cam acting on the tappet of a position detection device and pushes this with its cam contour more or less into the housing of the position detection device depending on the rotational position.
  • Two corresponding mechanical position detection devices can also be provided which are assigned to the same cam.

  • Rail vehicle coupling with a metal detector which is arranged in the upper area on the front of a faceplate in order to detect a coupling hook made of metal when it is inserted into the faceplate.
  • the present invention is based on the object of specifying an automatic air coupling for a rail vehicle, the automatic air coupling being easy to use, being robust at the same time, and in particular also meeting the requirement of air couplings for rail vehicles in the form of freight cars.
  • the object according to the invention is achieved by an automatic air coupling with the features of claim 1.
  • the dependent claims describe advantageous and particularly expedient embodiments of the invention and an automatic pull coupling with an automatic air coupling according to the invention.
  • the automatic air coupling for a rail vehicle according to the present invention wherein the rail vehicle is designed in particular in the form of a freight wagon, has a mouthpiece for coupling the air coupling to an air coupling of the same type, in accordance with the generic design explained at the beginning, and also a compressed air connection for connecting the air coupling to a Rail vehicle compressed air system and a flow channel that connects the mouthpiece to the compressed air nozzle in a compressed air-conducting manner.

In particular, a main air line, of which the flow channel forms a part, is blocked accordingly.

  • the rotatable shaft is provided with at least one cam, which can be made integral with the shaft or rotatably mounted on the shaft. The at least one cam engages at least indirectly on the valve body to actuate it.
